3.1 Menene Babban Fa'idodin Alumina Spherical?

Fa'idodin Alumina na Spherical suna da ban tsoro da gaske. Da farko, yana samun ma'aunin gwal na babban ƙarfin wutar lantarki (22-28 W / mK a 70% filler) tare da cikakkiyar rufin lantarki - wani abu na yau da kullun ba zai iya daidaitawa ba. Na biyu, tsarin halittarsa ​​na zagaye yana ba da damar iya adadin masu cikawa har zuwa 70%, yana ba da 30% mafi kyawun aikin zafi fiye da alumina mara daidaituwa a cikin kaya iri ɗaya. Na uku, yana rage farashin masana'antu ta hanyar rage sharar gida da daidaita aiki (babu buƙatar hanyoyin watsawa masu rikitarwa). Na hudu, yana faɗaɗa tsammanin rayuwa ta hanyar hana lalatawar zafi - rage yawan gazawar da kusan 35% a cikin aikace-aikacen damuwa mai girma. A ƙarshe, yanayin rashin aikin sa yana sa wasu dacewa cikin masana'antu, daga na'urorin lantarki zuwa sararin samaniya. Wannan ba sabuntawa ba ne - juyin juya hali ne.

3.2 Menene Iyakancin Alumina Mai Girma?

Maƙasudin farko shine ƙaramin ƙimar kuɗi na farko idan aka kwatanta da madaidaicin alumina fillers-wani matsala da ke da rauni idan aka kwatanta da tanadin kuɗi na dogon lokaci. Bugu da ƙari, masana'anta suna buƙatar ƙwararrun kayan aikin ɓata, yana iyakance isa ga wasu wurare. Hakanan akwai ƙaramin lanƙwan ganowa ga masu samarwa don haɓaka sigogin sarrafawa don ɓangarorin zagaye. Koyaya, waɗannan ɓangarorin suna da matuƙar ɓarna ta ƙimar ingancin kayan: kashe kuɗin kowace watt na gudanarwar thermal yana raguwa sosai sakamakon raguwar gazawa, tsawaita rayuwar abu, da ingantaccen masana'anta. Ga masu zane-zane masu tunani na gaba, wannan ba jarin kudi ba ne - ba sulhu ba.

4. Yankunan Aikace-aikacen Alumina Spherical

Spherical Alumina yana canza masana'antu inda ba za a iya sasantawa da sarrafa zafi ba:

Na'urorin lantarki: Samfuran masu amfani da zafin jiki (TIMs) don wayoyin hannu, LEDs, da abubuwan wutan lantarki - kayan aikin adana 20% mai sanyaya ba tare da kwata-kwata barazanar gajeriyar hanya ba.

Kamfanin mota: Batirin mota na lantarki yana kwantar da tsarin da manyan fitilun gaban LED, inda kwanciyar hankali na zafi ya shafi tsaro da inganci kai tsaye.

Wannan samfurin ba alkuki bane - shine tushen ƙira na gaba a duk faɗin duniya.

5. Ma'auni na Zinariya: Ƙarƙashin Ƙarfafa Ratio na Alumina Mai Girma

Haƙiƙanin hazaka na Alumina ya dogara da ikon sa na isar da wutar lantarki da kuma rufi a babban ma'aunin filler - warware matsalar mafi daurewar sashin. Filayen al'ada suna buƙatar ciniki mara daɗi: karafa suna gudanar da zafi amma suna haifar da gajerun da'irori, yayin da insulators kamar silica sadaukar da ingancin zafi. Spherical Alumina yana rushe wannan yanayin. Tsarin zagayensa yana haɓaka kauri, cibiyar sadarwar thermal mai haɗin haɗin gwiwa a 65 – 70% filler loading, yana ba da damar tafiyar da yanayin zafi na 22-28 W/mK yayin da yake riƙe da cikakkiyar keɓewar lantarki.

Wannan ba ilimi ba ne - an tabbatar da shi a wurin aiki. A cikin manyan abubuwan LED masu ƙarfi, Spherical Alumina yana haɗa ƙananan matakan zafin aiki da 18 ° C idan aka kwatanta da magunguna na tushen silica, tsawaita tsawon rayuwa da 40% da kawar da rufewar thermal. Don fakitin batirin motar lantarki, yana ba da damar mafi ƙarancin, tsarin kwantar da iska wanda ke guje wa zafi fiye da kima ba tare da ƙara nauyi ba. Abubuwan da ke faruwa suna da yawa: na'urori na iya zama ƙarami, sauri, kuma mafi ƙarfi - ba tare da iyakancewar zafi ba.

Injiniyoyi ba sa buƙatar zaɓar tsakanin aiki da aminci da tsaro. Spherical Alumina yana ba da ma'aunin gwal- sabis ɗin jituwa inda tasirin zafi da tsaro na lantarki ke kasancewa tare. Wannan ba abu ne kawai ba; abu ne mai kara kuzari don ci gaba wanda ke buɗe sabbin iyakoki a cikin shimfidar wuri.

Yarda da daidaito. Yarda da ci gaban. Spherical Alumina ba shine gaba ba - zaɓin da kuka kasance kuna jira ne.
